..are you refering to the one below? a french friend passed me these two old photos of an ex-French Navy F60L Ambulance that seemed to be in a static display in a collection or a Museum.
Just speculating, but to me it looks like the For Freedom museum in Knokke, Belgium....they have a nissen hut with vehciles , most of which are on loan.
